SPECIFICATION forming part of Letters Patent No. 259,608, dated June 13, 1882.

v Application filed January 10,1882. (No model.) Y

To all whom it may concern:

Be it known that I, EZRA W. VANDUZEN, a citizen ot the United States, residing at the cit)7 of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Smoke-Consuming Furnaces, of which the following is a specification.

This invention relates to improvements in the means employed for promoting combustion and preventing smoke in boiler-furnaces and the invention consists in the combination ot' a steam-injector pipe and a gas-suppl y pipe both tapping and terminating in the uptake or chimney of the furnace, aninjector and a transverse distributing-pipe connected with the injector and arranged along the front of the grate in close proximity to a cluster of'independent airoriflces pierced in the front wall or door ofthe furnace, whereby air is supplied in small streams to be heated and distributed, all of which will appear more fully hereinafter.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a boiler-furnace with my improvement applied thereto. Fig. 2 is a longitudinal section of the same, partly in elevation. Fig. 8 represents a modied form of the plan shown in Figs. 1 and 2. Fig. 4 is a central longitudinal section of the furnace with the boiler and supply-pipes in elevation.

A represents the walls of the furnace; B, the boiler; C, the smoke-stack; D, the doors; E, the ash-pit; F, an injector; Gr, the steampipe tapping the steam-drum H, an air-pipe, which projects into the smoke-stack near the end of the boiler-nues.

J J represent bell-shaped openings into pipe H, through which air and gases enter. These are placed on the under sideto prevent particles of dust, &c., from entering and clogging the orifices. j

I represents the common air and steam distributing pipe. doors D, as shown in Fig. 1, or below the same, as shown in Figs. 3 and 4.

L represents the steam and air supply pipe projecting upward opposite a cluster of small 'air-oriees,m. The construction and arrangement and operation of theseoriiees andof the pipes I and L are fully described in another application of even date herewith.

It is obvious thateither method ot' admitting air may be used in connection with the steampipe G and gas-pipe H tapping the smokestack, and still obtain the advantages of my invention herein.

Having described my invention, what I claim as new is- In a boiler-furnace, the combination of the steam-injector pipe Gr, the gas-supply pipe H, tapping and terminating in the uptake C, the injector F, and the transverse distributingpipe I, connected with the injector and arranged along the front of the grate in close proximity to the clusterl of independent airoritices pierced in the front wall ot' the furnace, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
